Il Forte nella roccia - the Fort in the rock

The Valmorbia werke (1914-1915) was structured in 3 floors drilled into a hillrock overhanging the Vallarsa and accessible from NE.
The Austrian-Hungarian Corps of Engineering hollowed out a deep fosse that was controlled by a firing place, provided with machine guns and rifles placed in a concrete building on the NE edge.A cave system dig into the rock gave access to the heart of the fort that, starting from a horseshoe like tunnel, where troups and provisions were allocated, was further structured along connections leading to the firing places and to the floodlights leaning on the valley.
The lower floor was structured in the same way while, in the heart of the hillrock, a wide vertical well gave access to the upper floor where batteries were allocated : it was a huge reinforced concrete block where 2hardened rotating domes (Skoda steel) and an observation post were going to be posted.
In 1915, at the startup of the war, works were still in progress and were never ended : now all that lasts is this uncredible silent example of military engineering
